DESCRIPTION
"The MIB module for managing UDP implementations.
Copyright (C) The Internet Society (2005). This
version of this MIB module is part of RFC 4113;
see the RFC itself for full legal notices."
REVISION "200505200000Z" -- May 20, 2005
DESCRIPTION
"IP version neutral revision, incorporating the
following revisions:
- Added udpHCInDatagrams and udpHCOutDatagrams in order
to provide high-capacity counters for fast networks.
- Added text to the descriptions of all counter objects
to indicate how discontinuities are detected.
- Deprecated the IPv4-specific udpTable and replaced it
with the version neutral udpEndpointTable. This
table includes support for connected UDP endpoints
and support for identification of the operating
system process associated with a UDP endpoint.
- Deprecated the udpGroup and replaced it with object
groups representing the current set of objects.
- Deprecated udpMIBCompliance and replaced it with
udpMIBCompliance2, which includes the compliance
information for the new object groups.
This version published as RFC 4113."

-- The UDP "Endpoint" table.
udpEndpointTable OBJECT-TYPE
SYNTAX SEQUENCE OF UdpEndpointEntry
MAX-ACCESS not-accessible
STATUS current
DESCRIPTION
"A table containing information about this entity's UDP
endpoints on which a local application is currently
accepting or sending datagrams.
The address type in this table represents the address
type used for the communication, irrespective of the
higher-layer abstraction. For example, an application
using IPv6 'sockets' to communicate via IPv4 between
::ffff:10.0.0.1 and ::ffff:10.0.0.2 would use
InetAddressType ipv4(1).
Unlike the udpTable in RFC 2013, this table also allows
the representation of an application that completely
specifies both local and remote addresses and ports. A
listening application is represented in three possible
ways:
1) An application that is willing to accept both IPv4
and IPv6 datagrams is represented by a
udpEndpointLocalAddressType of unknown(0) and a
udpEndpointLocalAddress of ''h (a zero-length
octet-string).
2) An application that is willing to accept only IPv4
or only IPv6 datagrams is represented by a
udpEndpointLocalAddressType of the appropriate
address type and a udpEndpointLocalAddress of
'0.0.0.0' or '::' respectively.
3) An application that is listening for datagrams only
for a specific IP address but from any remote
system is represented by a
udpEndpointLocalAddressType of the appropriate
address type, with udpEndpointLocalAddress
specifying the local address.
In all cases where the remote is a wildcard, the
udpEndpointRemoteAddressType is unknown(0), the
udpEndpointRemoteAddress is ''h (a zero-length
octet-string), and the udpEndpointRemotePort is 0.
If the operating system is demultiplexing UDP packets
by remote address and port, or if the application has
'connected' the socket specifying a default remote
address and port, the udpEndpointRemote* values should
be used to reflect this."

::= { udpEndpointEntry 1 }
udpEndpointLocalAddress OBJECT-TYPE
SYNTAX InetAddress
MAX-ACCESS not-accessible
STATUS current
DESCRIPTION
"The local IP address for this UDP endpoint.
The value of this object can be represented in three
possible ways, depending on the characteristics of the
listening application:
1. For an application that is willing to accept both
IPv4 and IPv6 datagrams, the value of this object
must be ''h (a zero-length octet-string), with
the value of the corresponding instance of the
udpEndpointLocalAddressType object being unknown(0).
2. For an application that is willing to accept only IPv4
or only IPv6 datagrams, the value of this object
must be '0.0.0.0' or '::', respectively, while the
corresponding instance of the
udpEndpointLocalAddressType object represents the
appropriate address type.
3. For an application that is listening for data
destined only to a specific IP address, the value
of this object is the specific IP address for which
this node is receiving packets, with the
corresponding instance of the
udpEndpointLocalAddressType object representing the
appropriate address type.
As this object is used in the index for the
udpEndpointTable, implementors of this table should be
careful not to create entries that would result in OIDs
with more than 128 subidentifiers; else the information
cannot be accessed using SNMPv1, SNMPv2c, or SNMPv3."

DESCRIPTION
"The address type of udpEndpointRemoteAddress. Only

unknown(0) if datagrams for all remote IP addresses are
accepted. Also, note that some combinations of
udpEndpointLocalAdressType and
udpEndpointRemoteAddressType are not supported. In
particular, if the value of this object is not
unknown(0), it is expected to always refer to the
same IP version as udpEndpointLocalAddressType."

DESCRIPTION
"The remote IP address for this UDP endpoint. If

Otherwise, it has the type described by
udpEndpointRemoteAddressType and is the address of the
remote system from which datagrams are to be accepted
(or to which all datagrams will be sent).
As this object is used in the index for the
